pro’s and con’s of ThermoLuminescence Dosimetry (TLD) with LiF as phospor pro’s - small dimensions - little volume averaging

con’s - high accuracy (1-2%) requires careful procedure and skilled operator - single point - batch of chips: distribution of sensitivities - fading - reading not directly available - labor/reading - no record (in contrast to film)

- suited for anthropomorphic phantoms - powder/thin films: measurements in build-up or transition regions - LiF: small energy dependence in MV range - large dose range: < mGy  > kGy - dose-rate independent - re-usable (in contrast to film)
